Thanks for the video

it would be good If the video was in landscape mode. we could see more file contents and there will be less word breakings.

He/she runs off to online forums to bicker about which {distro, WM, DE, text editor} is best, and how all others are unfathomably inferior, fundamentally broken abominations?

Or ... oh, sorry, I thought you meant something else.

Don't forget learning about systemd and then immediately deciding you actually don't like it and would prefer something else

Of all the things I've wondered about my Linux install... this was not really one of them, no
